摘要:

單原子催化劑（single atom catalysts, SACs）由于其高催化活性、良好穩(wěn)定性等優(yōu)點，在電化學(xué)領(lǐng)域得到廣泛研究。單原子催化劑不僅提供了研究催化反應(yīng)機理的新見解與思路，還在均相與非均相催化反應(yīng)連接方面起到了重要的作用。為了減少單原子催化劑在合成過程中出現(xiàn)聚集、原子利用率低等問題，總結(jié)和歸納了單原子催化劑的載體并介紹了單原子催化劑的合成方法；介紹了電催化析氫反應(yīng)（hydrogen evolution reaction, HER）的機理；對于電催化析氫反應(yīng)，重點介紹了Pt、Pd、Ru、Co、Mo、Ni金屬單原子，單原子合金和非金屬單原子在內(nèi)的單原子催化劑的催化活性，并分析了其電催化性能提高的原因。結(jié)果表明，單原子催化劑的制備已經(jīng)實現(xiàn)了從貴金屬單原子催化劑向非貴金屬單原子催化劑的演變。最后，還對單原子催化劑研究存在的問題進(jìn)行了分析，并對單原子催化劑的發(fā)展前景做了展望。

Abstract:

Single atom catalysts (SACs) have been widely studied in the field of electrochemistry due to their high catalytic activity and excellent stability. SACs not only provide new ideas for the study of catalytic reaction mechanisms, but also provide a bridge between homogeneous catalysis and heterogeneous catalysis. In this review, in order to reduce the aggregation and low atom utilization of SACs during the synthesis process, the carrier of SACs was summarized, besides, the synthesis methods of SACs and the mechanism of the electrocatalytic hydrogen evolution reaction (HER) were introduced. For the electrocatalytic hydrogen evolution reaction, the catalytic activity of SACs, including Pt, Pd, Ru, Co, Mo, Ni, single atom alloys and nonmetallic single atom were emphatically introduced, and the reasons for the improvement of their electrocatalyst performance were analyzed. The results show that the preparation of SACs has realized the evolution from noble metal SACs to non-noble metal SACs. Finally, the existing problems of SACs research were analyzed, and the development prospect of SACs was discussed.
